Background: Though integration of the pre-procedual computed tomography images of the LA with 3D electroanatomical maps has been developed to faciltate atrial fibrillation (AF) procedure, registration error can arise from interval changes in the heart size because of defferences in rhythm, rate, contractility, or fluid status. The purpose of this study was to evaluate the utility of rotate 3D angiography with CARTO 3 guided pulmonary vein isolation (PVI). Methods: This study included 53 paroxysmal AF patients who were received rotate 3D angiography (Innova 3131-IQ Biplane; GE Healthcare) with CARTO 3 guided PVI procedure (group-A) and with only CARTO 3 guided PVI procedure (group-B). After the PVI procedures, all patients underwent a right cavotricuspid isthmus ablation. Procedure and fluoroscopy parameters were recorded in all patients. Results: There were 7 patients in group-A and 46 patients in group-B. Total fluoroscopy time was statistically shorter in group-A than group-B (56±13 min vs. 72±20, p<0.05). There were no significant differences in the other parameters between two groups. No major complications occurred in both groups. Conclusion: Use of a rotate 3D angiography with CARTO 3 system was significantly lower fluoroscopy duration and usuful method during catheter ablation for AF.
